Our all new Fat 45 Carbon Clinchers - a game changer in the Planet X wheel range. They're the fastest, most aerodynamic and downright stealthy wheels we've ever produced. You won't find a higher performance wheel at this price.
Why the Fat 45? well, these are 23mm wide rims (our other ones are 19.5mm) Giving you a wider, shorter tyre contact patch, reducing the rolling resistance in the process. The fat rim produces a more rounded tyre shape, that when coupled with the shorter toroidal rim means a dramatic advancement in aerodynamic performance. This is most apparent when encountering the dreaded sidewind; the Fat 45 stays balanced, meaning the side force on the front part of the wheel is equal to that on the back, giving you far greater stability .
These wheels are as lightweight as you'd expect too, weighing in at 825g for the front, 976g for the rear. Not only are they good on the climbs, they will be lethal on the flat.
Of course, you want to know what this all means in the real world. Well, over the distance of an Ironman cycling section, the Fat 45's will save you 3 minutes compared to your old alloy's...
